"[The divorce] is news to you and everyone else, but for Guy this has been a long time coming," the friend adds. "I think he's sort of relieved that it's all out there. He doesn't have to fake it anymore."

Ritchie is "very excited about his film, and he's focused on that and getting on with it," says the pal. "For him, everything is really the same as before, only with more photographers. Yesterday was insane."

As for the kids – Lourdes, 12, Rocco, 8, and David, 3 – the friend says, "They're great. They are Guy and Madonna's top priority. That's all that needs to be said."
